The fact that this is written in Java knocks it noteworthiness down tenfold.
I just can't take java software seriously these days. Sorry. It's not you, it's me.
I just searched through the FreeBSD ports tree's list of java software and I can't find any that I would ever need.
I can, however, say my experience with java software in the last 15 years has consistently been negative. Every vendor provided software product that was java based has been especially painful. A recent example: I'm looking at you, Ubiquiti. (Who also uses MongoDB which requires manual intervention for crashed databases -- unacceptable to not be using an ACID database)
Also, I think android at least sort of qualifies.
Java is just more noticeable. It's the new client-side business app platform, and there are a ton of UI toolkits that scream "This is a Java app!"
But on the other side of the token, some of the best software I've used has been written in Java. Tons of Android apps, along with all the JetBrains IDEs (I love PyCharm), and Mirth Connect - software for processing HL7 that one of my company's products relies on heavily.
